Chemical compound
Osmium(V) chloride is an
inorganic chemical compound of
osmium metal and
chlorine with the chemical formula OsCl5 .
[3]
[4]
Potential synthesis
Osmium(V) chloride can be obtained in small amounts by reacting
osmium hexafluoride with excess
boron trichloride :
[5]
2OsF6 + 4BCl3 → 2OsCl5 + 4BF3 + Cl2
It can also be obtained by the action of
sulfur dichloride on
osmium tetroxide :
[2]
2OsO4 + 8SCl2 + 5Cl2 → 2OsCl5 + 8SOCl2
Physical properties
Osmium(V) chloride forms a black dimeric solid, isomorphic with
rhenium(V) chloride . OsCl5 is sparingly soluble in non-polar solvents.
[2] It is soluble in
POCl3 to form a red-brown solution, which can crystallize OsCl5 ·POCl3 .
